Ben Manes commented on CASSANDRA-11452:
---------------------------------------
Yes, a custom interface to define a {{longHashCode()}} would work, but that
doesn't seem to be a good general solution. I hope one day Java adds it onto
Object.
I was playing with a [randomized
W-TinyLFU|https://github.com/ben-manes/caffeine/commit/92f92f7a79a991d148cc88c9e691030dcebba22b]
earlier today. It works well. A random walk in Caffeine (as is) would be a
little concerning since that is a linked list traversal.
Cycling the victim through the probation passes Branimir's test and is my
preference so far. I need to run more simulations to ensure it doesn't have any
surprising results.

> Following up from CASSANDRA-5863, to make best use of caching and to avoid
> having to explicitly marking compaction accesses as non-cacheable, we need a
> cache implementation that uses an eviction algorithm that can better handle
> non-recurring accesses.
